Function Introduction:
1. Real time control of PWM signal output by writing duty cycle and frequenc
through registers
2. Support continuous output and specified pulse number output
3. The duty cycle and frequenc of all four channels are independently adjustable
4. Power on output function, automatically outputting saved values when powered on
5. The amplitude voltage can be set to 5V or the supply voltage
6. Anti reverse connection of power supply, anti static surge of 485 interface
7. Recommended 9~24V power supply, maximum 7~30V
8. Industrial grade quality, watchdog ensures 24-hour stable operation, wide temperature range of -40~85 to adapt to various environments
